I have edited this recent question that had the deprecated (geometry) tag: Do Minkowski sums have anything like calculus? Maybe somebody has some suggestions how to improve the choice of tags.

Is there anything resembling differential calculus over the space of (nicely behaved) regions in $\mathbb{R}^d$, where addition is interpreted in terms of Minkowski sums? For example, it is known that Minkowski sums act linearly on the perimeter of two-dimensional convex bodies. Is there any se...

Here is another recent question with a deprecated tag: Two convex sets' intersection in a discrete domain. The tag (set-theory) does not seem like a suitable tag for this question, either.

I'm considering a set which is described by the intersection of two convex sets in a discrete domain. We assume that the sum of elements of each vector is the same. For instance, $S = \{(2, 2, 2, 2), (3, 2, 2, 1), (2, 3, 2, 1), (2, 2, 3, 1), (3, 2, 3, 0)\}$ is not convex set in a discrete sense b...

I will mention that the tag (discrete-mathematics) is deprecated on MathOverflow, see the tag-info. Also, it is recommended to include at least one top-level tag. I will leave the choice of tags to more experienced users (and to the OP). — Martin Sleziak 2 mins ago

All right, thank you. — Sato 48 secs ago

I disagree on your idea that someone can decide the capitalization of their own name. See for instance the take of this of this Washington Post copy editor: http://www.theslot.com/webnames.html
The above was in connection with MathOverflow vs. Mathoverflow. It seems that the same link came up in connection with colors in names.
I had cause to do exactly the abuse in my previous comment, here: mathoverflow.net/questions/313527/… as there is a proof assistant whose correctly formatted name involves half of the letters coloured red. — David Roberts Oct 24 '18 at 21:44
@DavidRoberts I don't like it either. I more or less agree with this article on this kind of stunts in logos and names. — Federico Poloni Oct 25 '18 at 7:56
